CD74HC93E

Counter Dividers Overview

The CD74HC93E is a high-speed CMOS logic integrated circuit manufactured by Texas Instruments, belonging to the 74HC series. It functions as a 4-bit binary counter with asynchronous reset capability. The device features four independent flip-flops triggered on the negative edge of the clock signal. It operates within a supply voltage range of 2 V to 6 V and supports through-hole mounting in a standard 14-pin PDIP package. The component is designed for applications requiring reliable binary counting and frequency division across a wide industrial temperature range.

Counter Dividers Feature Summary

• Asynchronous reset functionality allows immediate clearing of all counter stages regardless of clock state
• Negative-edge triggering ensures precise synchronization with falling clock transitions
• High-speed CMOS technology enables operation across a broad voltage spectrum from 2 V to 6 V
• Industrial temperature rating supports stable performance in extreme environmental conditions

Counter Dividers Applications

• Digital frequency division circuits
• Binary counting sequences in digital systems
• Timing control logic modules
• Address generation in memory systems

Counter Dividers Procurement Notes

Verify the specific suffix 'E' confirms the PDIP-14 through-hole package variant distinct from surface-mount versions. Confirm RoHS compliance status via the manufacturer's official documentation before procurement. Ensure the ordering part number matches the exact logic family requirements for your design.

Counter Dividers Selection Notes

Select this component when a through-hole 4-bit binary counter is required for prototyping or legacy board designs. The HC series offers compatibility with standard 5 V logic levels while supporting lower voltage operation down to 2 V. Consider the PDIP-14 footprint constraints and verify pinout alignment with existing schematic layouts during integration.

Counter Dividers Part Context

This component is part of the Texas Instruments 74HC logic family, widely used for general-purpose digital logic applications. The 74HC93 specifically addresses the need for compact binary counting solutions. It serves as a fundamental building block in sequential logic design, often paired with decoders or other counters to create complex timing structures.

Counter Dividers FAQ

How is the reset function implemented in the CD74HC93E?

The reset is asynchronous, meaning it clears all flip-flop outputs immediately upon activation, independent of the clock signal.

What is the trigger type for the internal flip-flops?

The flip-flops are triggered on the negative edge of the clock input signal.
